1.Easy
t (s)v (m/s)7 sv = ?

A car moving at 6 m/s speeds up with a constant acceleration of 2.5 m/s² for 7 s. Find its final speed v.

v₀ = 6 m/sa = 2.5 m/s²t = 7 s
v = m/s
2.Easy
t (s)v (m/s)9 sv = ?

A car moving at 14 m/s speeds up with a constant acceleration of 4 m/s² for 9 s. Find its final speed v.

v₀ = 14 m/sa = 4 m/s²t = 9 s
v = m/s
3.Medium
t (s)v (m/s)t = ?33.33

A car driving at 120 km/h brakes with a constant deceleration of 3 m/s² until it stops. How long does braking take? Find t.

v₀ = 120 km/ha = −3 m/s²v = 0
t = s
4.Medium
t (s)v (m/s)4.167 s25

A car driving at 90 km/h brakes with a constant deceleration of 6 m/s² until it stops. Find the braking distance s.

v₀ = 90 km/ha = −6 m/s²v = 0
s = m
5.Hard
v₀ = 16 m/s30 m

A ball is thrown straight up at 16 m/s from the edge of a roof 30 m above the ground. Ignore air resistance and use g = 9.81 m/s². How long after the throw does it hit the ground? Find t.

v₀ = 16 m/sh₀ = 30 mg = 9.81 m/s²
t = s
6.Hard
v₀ = 7 m/s5 m

A ball is thrown straight up at 7 m/s from the edge of a roof 5 m above the ground. Ignore air resistance and use g = 9.81 m/s². How long after the throw does it hit the ground? Find t.

v₀ = 7 m/sh₀ = 5 mg = 9.81 m/s²
t = s

Answer key

  1. 1. v = 23.5 m/s
  2. 2. v = 50 m/s
  3. 3. t = 11.11 s
  4. 4. s = 52.08 m
  5. 5. t = 4.593 s
  6. 6. t = 1.95 s
